BRICK-MOLD SANDER.

SPECIFICATION forming part of Letters Patent No. 469,400, dated February23, 18592. Application tiled October 1, 1891. Serial No. 407,473. (Nomodel.)

ATo @ZZ whom, it may concern:

Be it known that we, JOHN FARNEN and JOHN MULLOY, citizens of the UnitedStates,

- both residing at Chicago,in the county of Cook and State of Illinois,and have invented certain new and useful Improvements in Machines forSanding Brick-Molds, of which the following is a specification,reference being had to the accompanying drawings, in which- Figure 1is'a central longitudinal vertical section, and Fig. 2 is a verticalcross-section.

Our invention relates to machines for sanding brick-molds preparatory totheir being refilled with clay.

The objectof our invention is to provide an improved sanding-machinewhich will be adapted to be operated in connection with a machine foremptying the molds after they have been lled, such as the machine shownand described in our application iiled May 22, 1891, Serial No. 393,779.l

We accomplish our object as hereinafter specified and as illustrated inthe drawings.

That which we regard as new will be pointed out in the claims.

In the drawings, 1 indicates the sander, which is somewhat cylindricalin shape. The

exterior of the sander consists of a thin sheet of metal or othersuitable material, which incloses the various parts of the sander. Anopening 2 is provided at the upper portion of the sander, which openingis of such size and shape as to permit of the introduction of a mold.

3 and 4 indicate disks of woodorother suitable material, which form theends of the sander. Upon each end, at the interior of the sander, areformed tianges 5 and 6, which are spirally arranged to form guides forthe molds after they have been introduced into the sander. The flanges 5and 6 are so arranged that as the mold is moved around in the sander itwill assume the various positions indicated in Fig. 2 and will finallybe carried to the point 7, when it will be ready to be withdrawn fromthe sander.

8 indicates a shaft, which is mounted cen# trally in the sander andextends longitudinally through it,being journaled in suitable bearings.A sprocket-wheel 9 is mounted upon one end of the shaft, or instead of asprocket-wheel a pulley may be used.

VMounted upon and keyed to the shaft 8 are wheels 10, which are adaptedto be rotated by the rotation of the shaft 8. Each of the wheels 10 isprovided with arms 11 and 12, which are at such a distance apart thatthey will receive a mold between them, as best shown in Fig. 2, and theyare of such length that when a mold is placed upon the sander at theopening 2 it will be engaged by one of the arms 12 and moved into theopening 2. We prefer to use two wheels l0, one located `near each end ofthe sander; but a greater number may be used, if desired. The innerportion of the hub of each wheel l0 is recessed and beveled, as shown at13 in Fig. 1, anda sleeve 14 is fitted upon the shaft 8 between saidhubs, the ends of the sleeve being beveled, so that they will fit snuglyinto the recesses in the hubs of the wheels 10. By this construction thesand in the sander will be prevented from falling upon the shaft S.

15 indicates an opening in one end of the sander opposite the point 7,through which the molds are withdrawn after being sanded.

16 indicates a carriage, which is adapted to move upon horizontal guides17, which are suitably supported on'a level with the opening 15 at eachside of the carriage.

18 indicates a dog, which is pivotedl to the inner end of the carriage16 and is provided with an arm 19, which extends at right angles to it.

2O indicatesaspring, which at one end is connected to the arm 19 and atthe other toa lug 2l upon the inner end of the'carriagelt, as best shownin Fig. l. The dog 18 is adapt` ed to engage a bar 22 upon the end of amold 23. All the molds are provided with a rod 22 or some similar deviceadapted to be seized for the purpose of drawing the mold out of thesander.

The carriage lis connected to a lever 24 by means of a connecting-106125in such manner that by operating the leverm24 the carriage 16 will bemoved back and forth upon the guides 17.

26 indicates a rock-shaft, which is provided with an arm 27, connectedto the lever 24 by a connecting-rod 28. By this construction as theshaft 26 is rocked the lever 24. will bereciprocated and the carriage 16will be moved back and fort-h upon the guides 17.

29 indicates a cogged wheel, which is mounted upon the shaft 26 and isrotated alternately in opposite directions by means of a rack 30. Therack 30 is mounted in suitable guides in such mannerthat it will beadapted to be reciprocated vertically.

3l indicates a rock-shaft, which is mounted in suitable bearings and isconnected to the rack 30 by means of a connectingrod 32, which at oneend is connected to the rack 30 and at the other end to a crank-arm 33,mounted upon and keyed to the rock-shaft 31.

34 indicates a sleeve, which is mounted upon the shaft 31. The end ofthe sleeve 34 adjacent to the crank-arm 33 is provided withratchet-teeth adapted to engage similar teeth upon the inner portion ofthe crank-arm or upon the shaft, the arrangement being such that as theshaft 3l is rocked the sleeve 34 -Will be intermittently rotated.

35 indicates a sprocketwheel, which is mounted upon the sleeve 3i and isgeared to the sprocket-wheel 9 by means of a chain 3G. When a pulley isused instead of the Wheel f), a pulley may also be used instead of thewheel 35, and the two pulleys may then be connected by a belt. Anysuitable mechanism may be provided for rocking the lshaft 3l. By thisconstruction when the shaft 3l is rocked the sleeve 34will be made torotate intermittently and an intermittent rotation imparted to theWheels l0. The molds in the sander will thereby be moved intermittentlyaround the interior of the sander, and the adjustment of the variousparts is such that when the molds arrive at the point 7 opposite theopening l5 the Wheels 10 willremain stationary for asnfficient length oftime to permit of the withdrawal of the molds from the sander.

The arrangement of the carriage 16 and dog 18 is such that when a mold23 arrives at the point 7 in the sander the carriage 1G will move tosuch position that the dog 18 will engage the bar 22 upon the end of themold, and the carriage will then be moved outward, drawing the mold outof the sander.

A quantity of sand is placed in the interior of the sander, and themolds are introduced into the sander in an inverted position. As theymove to the lower portion of the sander upon the anges 5 and they willtake up a` quantity of the sand, which will be scattered.

over theinteriorof the molds as they continue to move around upon theflanges until they again reach the upper part of the sander, When theywill be again upturned and the sand will be permitted to fall back intothe lower portion of the sander.

In order to prevent the sand which falls out of the molds @from fallinginto the sanded molds before they are withdrawn from the sander, adeflecting-plate 37 is provided, which extends around the interior ofthe sander, as shown in Fig. 2. This deflectingplate preferably consistsof a continuation of a portion of the exterior covering of the sander.When more than two wheels 10 are used, itwill be necessary to divide thedeflector 37 into two or more parts to permit of the rotation of thewheels.

As hereinbet'ore stated, the sander above described is adapted to beused in connection with the machine described in our said formerapplication; but it may also be used alone or in connection with othermachines, if desired.
